love these vids.

Nice share.

@fermista:

I could be wrong here but as I see it the two gauges are two extremes between a continuous set of homotopic gauges. So... one can always be shifted into another in such a way that both are always true. The non-conserved equations also both 'exist' but they don't define any useful motion as such.

[fermista]

So using the magnetic vector potential gauge where the x-component of the momentum is conserved and the gauge where the y-component of momentum is conserved, we get the x and y components of the momentum of the origin of the particle's rotation respectively. Right, got that.

What I'm wondering is what is the physical significance of the non-conserved components of momentum for these gauges? Or are they just discarded as irrelevant somehow?

I am looking forward to this lecture tonight. My second month with classical physics grad education....thanks for the material professor.

You could go through a dozen books and still not get a good as grounding in modern physics as that you can get from Prof. Susskind. All we need from Stanford is a series of lectures on field theory and string theory. If any one can explain these Susskind can,

@luzzie9 rite on man . a field theory and string theory lecture series wud b fantastic!!!!!!!!!!! all things u need 2 go through many books 4 undrstandin, explaind in simple english by sum1 who practically knows evrythin u need 2 kno abt da subjct
